There's some testing, but it's not nearly as thorough and, frankly, I would be stunned, STUNNED, if the number of current NFL players on some sort of PED is anything less than 100%; just in football, nobody really cares. You're going to tell me a guy who tears his ACL in December comes back the very next year and rushes for 2,000+ yards? Come on. Those guys are all doping.

Yup. Baseball seems to be only of the 4 major American sports that takes testing seriously.
